A couple of thoughts, assuming this is true...
I don't doubt that Obekpa is a bit of a douche bag. And I can see how guys would get into it with him during practice if you have to play with him every day.
But that's different from jumping a guy in the lockerroom. That's not acceptable anywhere, in fact, it's criminal.
If a guy annoys you in practice, you spike the ball at him, push and shove ... your teammates break you up, and then life goes on. This has been happening in basketball for 100 years probably, and that's how you handle it.
